A powder grinding mill may either perform dry grinding or wet grinding. Dry grinding involves extremely dry raw materials and applies physical crashing or abrasion for grinding. Wet grinding on the other hand involves the use of chemicals for exceptionally fine grinding.
Raw mill fans: Raw mill fan in cement industry carries gas and raw meal. The pressure drop in raw mill fan is very high. If a vertical roller mill is used for raw grinding in cement industry then a large raw mill fan is installed. Usually cement industries use centrifugal fans to carry out this process. 4.

Powder processing system technological process: raw material will be transport to semiopen shed by special vehicle, and then be shoveled into the crusher to be crushed into particles smaller than 40mm. The material particles will be raised to the storage hopper by the elevator and then be evenly sent to the main mill for grinding by feeder.
